TRE'ATMEINTIOF PEA'T oa- THERFLIGNEQUS--SUBSTANCES.

SPECIFICATION forming part of Letters Patent Ho. I607,528, dated July19, 1898. Application filed June 1, 1897. Serial No. 638,921- (Ncspecimen): Patented in En land June 20, I89 N01 To all whom it mayconcern:'

Be it known that I, Ronnnr FERGUSSON STRONG, a subject of the Queen ofGreat Britain, and a resident of Victoria strcct, 705V .5 minstcr,London, England, have invented certain new and useful Improvements inthe Treatment of Peat or other Ligncous Substances, (for which I haveobtained a patent in Great Britain, No. 13,649, dated June 20,

I0 1896,) of which the following is a full, clear,

and exact specification thereof.

My invention relates to a new or improved process for the treatment ofpeat and other ligneous substances for producing paving- 15' blocks,slabs, tiles, slates, conduits, and fuel wherein the ingredients usedare peat, caustic alkaline earth, and pyroligneous acid combined insuitable proportions, according to the product required.

One of the objects of myinvention is the production of waterproof fuelfor household, industrial, and other purposes.

In carrying my invention into practice I use dry cat, s wdust, or otherligneous sub-v stances, 'w 10E are firstground or disintegrated, whenI'add thereto twenty to thirty per cent. or thereabout of causticalkaline earth-such asli e, dolom1 ,an t e 1 e the whole being I;orouglily mixed together.

To this mixture I further add ten percent. or

Moreover, it has, as compared withwood-pavingan'dasphalt,furtherimportantadvantages by providiugabetterfoothold for horses and exhibiting the antiseptic qualities of peat..

I may instead of blocks form slabs, flagstones, tiles, slates, and thelikc-ofthe same material, or Inlay use it in a plastic state to Onissuing from form .the upper uxq of 'ro ds, streets, and the like, inwhich case Ireduce the blocks prepared in the manner above describedinto powder aud'applyit as found desirable.

In the manufacture of hriquets as fuel for household and industrialpurposes I add to the ground and dried peat or other ligneous substanceonly from one to two per cent. ofcaustic alkaline earth and about fiveper cent. of pyroligneousacid. 6o

In some cases the fuel is made in the form of peat-coke by adding to themass before compression three to fiveper cent. of silicate 0 o M of soda'.1n aguegus sglutign. The mass 18 then presse in theusualmann'er and issubsequently coked.

I may obviously vary the above proportions to a slight extent withoutdeparting from the na ure of this invention.

Having nowparticularly describeo'and ascertained the nature of my saidinvention and in what manner the same is to be perform cd, I declarethat what I claim is- 1. The herein described process for the treatmentof peat and other ligneous substances for the purpose set forth, whichconsists in adding to, and thoroughly mixing with, such ligneoussubstance,when in a; disintegrated condition, acaustic alkaline earth,

and then adding to, and thoroughly mixing 8'0 with such composition,pyroligneousacid,

substantially as described.
